The Los Angeles Kings caught fire offensively last postseason but were struggled mightily to score during the regular season.

The Kings averaged 2.3 goals per game during the regular season and struggled to find offensive continuity for long stretches of the season. Once Darryl Sutter came on board as head coach, the offense improved, but moving forward the Kings will be searching for goal scorers to help this offense.

The offensively balanced front line of Anze Kopitar, Dustin Brown and Justin Williams played solid hockey last season and would love to add another legitimate scorer to the mix this offseason.

Although most of the big-name free agents have signed, there are many valuable players on the market who could make an immediate impact.

Here are five players that the Kings should sign to help out their offense.

Shane Doan

The Kings should actively engage in the Shane Doan sweepstakes because of his ability to be a playmaker by adding immediate scoring to the Kings attack.

Last season, Doan scored 22 goals and notched 28 assists for the offensively challenged Phoenix Coyotes. Doan could add a touch on the power play with five goals last season and showed last postseason his toughness and determination that will translate anywhere.

If the Kings want to add one of the best scorers remaining on the market, while weakening the lineup of their division rival, the Los Angeles Kings must sign Shane Doan.

Ryan O'Reilly

Last season with the Colorado Avalanche, Ryan O'Reilly spotted career highs in goals (18) and assists (37) making him a very intriguing restricted free agent.

This centerman has uncapped potential and would flourish with the experienced Kings for years to come. Not only has O'Reilly scored more goals in each of his last three seasons but he scored 15 power-play points which is an extremely valuable skill to posses.

If the Kings want to add one of the best centers on the restricted free-agent market, they must make an offer for the 21-year-old prospect.

Jason Arnott

Jason Arnott may not be the 25-plus goal scorer he was from 2005-2008 but can still find ways to score for the Kings next season.

Last year in his 18th season, Arnott scored 17 goals and 17 assists for the St. Louis Blues. Arnott adds immediate value on the power play with his 6'5", 200 pounds frame that should allow him to build upon his 14-point special teams contribution from last season.

This combination of size, savvy and Stanley Cup experience would play right into the strengths of the defending Stanley Cup Winners.

Jamie Benn

After two consecutive tremendous seasons with the Dallas, 23-year-old Jamie Benn will be looking to cash in this offseason as a restricted free agent.

In 2010, Benn scored 22 goals and 34 assist in only 59 games. He then built upon that success last season by notching 26 goals and 37 assist in 71 games. Injury issues is a concern for potential but make no mistake, this mans production speaks for itself.

If Benn can stay on the rink, his plus-15 rating and 25-plus goal scoring ability would translate beautifully for the Los Angeles Kings. Dragging him away from Dallas will be pricey but the Los Angeles Kings would be foolish not to consider making an offer for his services this offseason.

Alexander Semin

Alexander Semin may have had a down year last season but if he could return to his 2009 form, the Los Angeles Kings would be adding a tremendous piece.

In 2009 Semin scored 40 goals and 44 assists, marking career year in points. 2010 and 2011 resulted in a similar 54-point fashion, which is part of the reason why teams remain hesitant to sign this talented forward.

Many concerns also surround his ability to play defense and hustle on a consistent effort but playing for the defending world champions could change his motivation in a heartbeat.

If the Los Angeles Kings want the most talented free agent on the market then they will pay, most likely a steep price, for Semin's services next season.
